Mailer Box

A  mailer box is a tried-and-true e-commerce box for subscriptions, influencer/corporate gifts, sales kits, and more. Get creative with how you want consumers to receive your custom-designed mailer. Custom-designed mailer boxes add extra value to your product and enhance your brand.

Mailer Box Product Details

We offer an array of options for customizable mailer boxes so you can create a box that perfectly resembles your brand identity and offers ultimate functionality. From inks to materials and sizes, choose what you prefer and design the perfect box. 

Why Choose Custom Mailer Boxes?

Mailer boxes, also known as subscription boxes (Roll End Front Tuck – REFT), are gifts that keep on giving. This box is the perfect option to use for subscriptions, gifts and e-commerce goods. Its stylish, durable design makes the box suitable to ship as is and does not require any additional outer shipping material — when your customers receive your box, your unique design will be front and center. It's easy to make a lasting impression with personalized mailer boxes. 

Custom design mailer boxes are a stylish yet simple packaging solution, as our online design studio makes it easy to create a gorgeous box, and you don't need tape or glue to assemble these boxes. 


Our digital printing process uses a CMYK color model with an extended color gamut for a wider range of color-matching possibilities. We capture and recycle unused or leftover ink. Leftover ink is locally treated and transformed into ready-to-use, reclaimed water — making our printing process environmentally friendly.

Our Materials

We make corrugated material from up to 99% post-consumer recycled material and provide the following finishes:

Kraft: This finish offers a natural brown look with a matte finish that's uncoated.

White: This uncoated finish offers a matte, bright white look.

Premium white: For a glossy finish, opt for a coated bright white box.

How to Design a Custom Mailer Box That Reflects Your Brand's Identity

DIYpack offers ultimate customization, as you can choose ink colors and finishes. Add patterns and images to your design to reflect your brand identity. It's also important to choose the right mailer box size. 

Selecting an appropriate mailer box size will keep your product secure. Your product should fit snugly to prevent it from moving around inside the packaging, as this can cause damage. A snug fit also means you don't have to use much void fill. 

Not all products need void fill, but you'll want to package fragile products, like ceramics, with void fill like tissue paper, packaging peanuts, bubble wrap or kraft paper. Ensure you have enough space in your box to include sufficient void fill for these products.
